Abstract
A method of integrated acousto-optic processor conceived for GPS signal acquisition is presented. Once the Doppler shift is resolved, the time of arrival is obtained quasi- instantaneously in this system. It is estimated an acquisition time of at most 1 ms. In this paper, the principle, design, structure of the integrated AO correlator are mainly described.
